Fireworks can be ignited in checked or carry-on baggage from the normal jostling of bags in flight due to friction rubbing against flammable material. Because they are considered so dangerous, FAA and international regulations ban them altogether from aircraft whether placed in checked bags, carry-ons or on the passenger.

Violations are dealt with strictly, with the FAA issuing stiff fines to violators. Penalties can include fines from $75,000 per violation to up to $175,000 per violation if death, serious injury or significant property damage occurs. In addition, violators may face substantial criminal fines and even jail time up to five years, with up to 10 years in the case of death or serious injury.

The FAA is also warning the public not to ship fireworks by air for the same reasons. More information on hazardous materials and other prohibited items can be found on the FAA's PackSafe website.
